Hi
It is absolutely impossible to repair a piece such as this when broken, you just can't do it unfortunately. You can indeed keep one of the piece as a separate sculpture but it just won't be the same. This sculpture is an expensive piece to replace as it is made using the Masello Technique in Northern Blue or Norte Boreale Crystal which is an incredibly difficult combination of glass to blow. If you need or wany any further information, please contact us via our website and we are more than happy to help
